Hudl 2 not found in Fastboot

[Guest thewanderer42]

Hello, I factory reset my Hudl2 which meant i had to upgrade before I could use it again

Problem Is it will not pass the integrity check, so i tried to flash tethered cwm but no matter what drivers or pc's i use it just wont be picked up in fastboot

What happens when you plug it into a USB2 ports on a computer in either fastboot mode or when you break out of the setup process and re-enable USB debugging in the developer mode?
